Schaller M6 Pin Guitar Tuning Machine

The Schaller M6 Pin guitar tuning machine features a refined 1:18 gear ratio that delivers exceptional precision, smooth operation, and tuning stability. Built with CNC-machined components and a self-locking drive mechanism, each unit ensures consistent, sensitive adjustments for demanding musicians.
Equipped with high-grade brass string posts engineered directly into the enclosed housing, these tuners are permanently lubricated with Schaller special grease for completely maintenance-free performance. The specialized stepped M6 flanged washer reliably centers the string post and eliminates tilting torque without requiring stepped headstock boreholes.
Engineered with a precise two-pin mounting design featuring a 0.39-inch pin-to-pin distance and an 0.31-inch post-to-pin spacing, this tuning machine drops directly into compatible modern headstocks for rock-solid stability.
